Application filed February 28, 1895. Serial No. 540,121. (No model.)

To all whom it may concern-.-

Be it known that 1, CHARLES SHEPHERD CAMERON ROCK, of New York city, inthe county an d State of New York, have invented a new and ImprovedAutomatic Coal-Delivcry, of which the following is a full, clear, andexact description.

lhe object of the invention is to provide a new and improvedcoal-delivery, more especially designed for use in dwellings, andarranged to enable atenant to automatically fill a bucket with coal froma coal-bin located in the cellar and to hoist the bucket to the floor onwhich it is to be used.

T he invention consists principally of a double-acting gate arranged inthe chute of the coal-bin, a lever connection for actuating the saidgate, and a bucket or other receptaclc serving to actuate the said levermechanism and adapted to receive a quantity of coal measured by the saidgate.

The invention also consists of certain parts and details, andcombinations of the same, as will be hereinafter fully described, andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both views.

Figurel is a sectional side elevation of the improvement as applied, and2 is a like view of the same with the parts in a different position.

From the coal-bin A, usually located in the cellar of a dwelling, leadsa chute B, opening into a shaft 0 built in the wall of the house, andextending to the floor or floors to which the coal is to be delivered.The chute B is adapted to discharge at its lower end into a bucket orother receptacle D, adapted to be raised and lowered in the shaft 0 bymeans of a suitable rope E and hoisting device F of any approvedconstruction. In the chute B is arranged a double gate G, pivoted at ornear its middle at G on a shaft journaled in the sides of the chute B,the said gate being provided at its upper end with a cut-oif flange Gand at its lower end with a stop-flange G as plainly shown in thedrawings. The outer end of the shaft forming the fulcrum G of the gate Gis provided with an arm H, connected by a link I with a lever Jfulcrunied at J and extending into the lower end of the shaft 0, theinner end of the said lever supporting a platform K adapted to receivethe bucket D, to support the latter while the coal is passing from thechute B into the bucket, as illustrated in Fig. 2.

Now it will be seen by reference to Fig. 1, that the gate G normally isin such a position that its cut-off flange G is raised above the flooror bottom of the chute B, while the other flange G is down in contactwith the bottom of the chute B, to stop the flow of coal from the bin Adown the chute B under the gate G. The platform K is now in an uppermostposition, and when a tenant desires a bucketful of coal he lowers thebucket from his floor by the rope E and hoisting device F, so that thebucket D finally rests on the platform K, and by its weight causes adownward movement of the platform K and a consequent upward swinging ofthe outer end of the lever J, whereby the link I moves the arm H upwardto turn the shaft G so as to impart a swing ing motion to the gate G,the latter then passing into the position shown in Fig. 2. In doing sothe cut-off flange G2 cuts off the coal at or near the mouth of the binA at the chute B, and permits the quantity of coal contained between theflanges G2 and G8 to slide down the chute into the bucket D, locatedwith its open end at or below the bottom of the lower end of the chuteB. When this measured quantity of coal has passed into the bucket D, theoperator by actuating the hoisting device F, raises the filled bucket Dto his floor for use. As soon as the filled bucketD moves away from theplatform K, then the weight of the lever J causes a downward swinging ofthe outer end of the lever, whereby the link I pulls the arm H downward,so that the gate G swings back to its normal position, (shown in Fig.1,) whereby the flange G is brought down in contact with the bottom ofthe chutewall and the upper flange Gr again opens the mouth of the binto permit coal from the bin to pass under the gate G. Theabove-described operation is again repeated as soon as the bucket isloaded in the manner above de scribed.

It is understood that a single coal-bin may be provided with two or morechutes B, each leading to a shaft containing a bucket for the differentfloors in the building, or separate bins, each provided with a chuteleading to a shaft, may be provided, so that each tenant can get his ownsupply of coal from his bin.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. An apparatus for discharging coal and consisting ofa coal-containing hopper, a discharge chute connected thereto andextending outwardly therefrom, a valve or gate commanding the flow inthe chute, a vertically extending link connected to the valve or gateand projecting downwardly therefrom, a lever to one arm of which thelink is connected, a weight fixed to the end of the lever to which thelink is connected, a table mounted on the V remaining arm of the lever,and a vertically movable bucket capable of descending upon the table andof depressing the lever to operate the valve or gate, the chute being soarranged that its contents will be emptied into the bucket,substantially as described.

2. In an apparatus for discharging coal, the combination of acoal-containing hopper, a chute communicating with the same, a shaftextending transversely through the chute, a plate located within thechute and fixed to the said transverse shaft, the said plate being of awidth equal to that of the chute and having at each of its extremities adownwardlyextending wing or projection, a crank arm fixed to thetransverse shaft, a link pivoted to the crank arm, a lever to one arm ofwhich the link is connected, a weight connected to that arm of the leverhaving the link, and a bucket capable of descending upon the remainingarm of the lever, the chute being adapted to deliver the coal directlyinto the bucket when so descended, substantially as described.
